SUBJECT: Soliciting comments on the proposed changes to the
 surface analyses and surface forecast charts through
 until May 24, 2017

The NWS National Centers for Environmental Prediction`s (NCEP)
Ocean Prediction Center (OPC), the National Hurricane Center`s
(NHC) Tropical Analysis and Forecast Branch (TAFB), and Weather
Forecast Office Honolulu are collecting comments until May 24,
2017, on a proposal to change the content of their surface
analyses and forecast charts.

- OPC is proposing to change the content of its surface
 analyses, and 24-, 48-, and 96-hour forecast charts.
- TAFB is proposing to change the content of its surface
 analyses and 72-hour forecast charts
- WFO Honolulu is proposing to change the content of its surface

The proposed changes would be for these charts to eliminate past
track information for all systems and to contain future forecast
track information only for extratropical low pressure systems
that have, or are forecast to have, hazards associated with
them.  The hazards displayed will be gale, storm, hurricane-
force, developing gale, developing storm, developing hurricane-
force, and possible tropical cyclone.  Heavy freezing spray
information and the ice edge will be included as well.

As proposed, the analysis and forecast charts will no longer
include past track information and forecast tracks for highs,
extratropical lows with none of the aforementioned hazards
associated with them or expected, and tropical cyclones.  This
change will improve OPC, TAFB and WFO Honolulu forecasters`
ability to provide detail in their digital forecasts. For OPC,
the change will provide flexibility in the OPC workflow to test
and potentially implement a 72-hour forecast chart.
Additionally, the change will ensure consistency of information
regarding tropical cyclones found through text and graphics
supplied by the NHC, Central Pacific Hurricane Center (CPHC),
and Joint Typhoon Warning Center (JTWC).

An example of the change can be found at:

At the site above, you can comment on the proposed change
through a link at the bottom of the page.

Through this comment solicitation, no changes will occur to the
schedule of radiofax charts produced by the OPC, TAFB, or WFO
Honolulu. There will be no effect on the schedule via the
Worldwide Marine Radiofacsimile Broadcast:

There will also be no changes to the Unified Surface Analysis
